GSM Basic Principles


The success of GSM technologies in turn, has given rise to optimistic scenarios for the evolution of 3G and 4G technologies such as UMTS and LTE.

We begin our journey by gaining an understanding about the underlying GSM technology, which was designed for easy roaming.

We then cover the most important enhancements to 2G-GSM, specifically GPRS and EDGE, which facilitate efficient access to packet data networks. 3G UMTS brings not only higher data rates but also better QoS, better security, multimedia and the possibility of fallback to 2G.

By learning this course, students can get knowledge on GSM Basic Principles, GSM Systems and its functions in different portions of the telecom world.
